- 1). Determine the spot on your roof that receives maximum sunlight. Mark the area with twine or chalk.
- 2). Use a stud finder to locate the rafters in that location on the roof. Mark each rafter using chalk.
- 3). Align panel mounts on top of the marked rafters. You can use a laser level to keep the mounts in a straight line.
- 4). Fit the pilot bit in the drill and make small holes in the rafters so they do not split during the installation process.
- 5). Anchor the panel mounts to the rafters using lag bolts. Leave at least 3 or 4 inches of space between the panels and the roof. This is necessary for air circulation.
- 6). Place metal flashing on top of each mount to prevent water from leaking through the roof.
- 7). Use 3/8 inch stainless bolts for attaching the metal rails to the panel mounts.
- 8). Slide the solar panels into place onto the rails and mounts. They will either snap or slide into place (check manufacturer's instructions for precision).
- 9). Have an electrician wire the panels together. The electrician will then connect them to a power inverter, which will be connected to the home grid. Many states do not allow the homeowners to do the wiring themselves.
